TECHNICAL FIELD

This disclosure relates to the field of information technologies, and inparticular to an apparatus and method for configuring a transmissionresource of a beam failure recovery request, apparatus and method forresponding a beam failure recovery request, and a communications system.

BACKGROUND

Massive multiple-input multiple-output (MIMO) technology is a keytechnology in a new radio (NR) system, which includes studies of thefrequency bands below 6 GHz and above 6 GHz. With the increase of thetransmission frequency bands, the fading and loss in the transmissionwill increase accordingly, and a beamforming technique becomes a keytechnique in the massive MIMO as it may effectively compensate for thefading.

At present, the beamforming technique includes analog beamforming (ABF),digital beamforming (DBF), and analog-digital hybrid beamforming (HBF).In the ABF, beamforming is performed on an analog domain, which is lesscomplex to implement than the DBF, but beamforming factors over theentire time domain symbols are identical. When the number of users isrelatively large, the ABF may impose certain restrictions on schedulingor user performance. In the DBF, the beamforming is performed on adigital domain, and each resource element in the time-frequency domainmay adjust the beamforming factor as needed, but the complexityincreases with the increase of the number of antennas, hence, it is notapplicable to a massive MIMO system. And the HBF is a compromise betweenthe ABF and the DBF in terms of performance and processing complexity,in which beamforming may be performed on both the analog and digitaldomains. However, the HBF is still limited to beamforming operations onthe analog domain, and the amount of beams supported on each symbol islimited.

In the study of the NR, in order to improve the reliability oftransmission, a beamforming technique in which multiple beams aresimultaneously transmitted for a physical channel (such as a broadcastchannel, a data channel, and a control channel, etc.) is allowed.However, in the multi-beam beamforming technique, there still exists acase of transmission failure, referred to as beam failure, due to atransmission characteristic of a high frequency band, rotation of amobile station, and occlusion of an obstacle, and the like, in whichcase by adjusting service beams, it is possible to solve a problem oftransmission failure at a physical layer and a media access control(MAC) layer. Therefore, a beam recovery mechanism is introduced in theNR: configuring physical resources for monitoring and/or pairs of beamsmonitored by the physical resources by the network equipment (e.g. atransmission point, TRP) for a user equipment, and the user equipmentmonitors a transmission state of pairs of beams of the control channelbased on the configured physical resources. In a case where the userequipment (UE) detects a transmission failure of the control channel(e.g. an NR physical downlink control channel, NR-PDCCH), it may notifythe network equipment (such as a transmission point) of transmissionfailure of a current link and/or a suggestion for new service beam pairsby transmitting an uplink signal, and the transmission point maycorrespondingly select new service beam pairs for the UE to recover thetransmission.

It should be noted that the above description of the background ismerely provided for clear and complete explanation of this disclosureand for easy understanding by those skilled in the art. And it shouldnot be understood that the above technical solution is known to thoseskilled in the art as it is described in the background of thisdisclosure.

SUMMARY

When multiple pieces of network equipment (such as transmission points,TRPs) serve UE, the multiple pieces of network equipment may transmitidentical data (such as joint transmission, JT), or may transmitdifferent data (such as non-coherent joint transmission, NC-JT). In sucha scenario, for a certain piece of UE, the UE is only connected to onepiece of network equipment. For the UE, the network equipment isreferred to as serving network equipment, and other network equipment isreferred to as coordination network equipment. For the case wheremultiple pieces of network equipment transmit different data (such asNR-physical downlink shared channels, NR-PDSCHs), a transmissionmechanism of multiple NR-PDCCHs is introduced into the NR, each NR-PDCCHrespectively scheduling NR-PDSCHs transmitted by different networkequipment.

It was found by the inventors that for a certain piece of UE, whenmultiple pieces of network equipment transmit different NR-PDSCHs andmultiple NR-PDCCHs are transmitted on multiple pieces of networkequipment, when an event of beam failure occurs in one of the pieces ofnetwork equipment, when no beam recovery or other operation is performedon the network equipment, it will result in the UE not be able toreceive data of the network equipment in which the event of beam failureoccurs, thereby affecting normal communications between the networkequipment and the UE. An existing recovery mechanism may be used as abeam recovery mechanism of the serving network equipment. However, sincethe coordination network equipment is not connected to the UE, RRCsignaling cannot be transmitted, and the amount of transmitted NR-PDCCHtypes may be limited in comparison with the serving network equipment.Hence, a beam recovery mechanism of the coordination network equipmentis different from the beam recovery mechanism of the serving networkequipment. Therefore, there is a need to design a beam recoverymechanism to deal with the case where beam failure occurs in thecoordination network equipment.

Embodiment 1

The embodiment of this disclosure provides a method for configuring atransmission resource of a beam failure recovery request, applicable toa network equipment side. FIG. 2 is a flowchart of the method forconfiguring a transmission resource of a beam failure recovery requestof Embodiment 1 of this disclosure. As shown in FIG. 2 , the methodincludes:

Step 201: configuration information is transmitted to user equipment,the configuration information being used to configure a transmissionresource of a beam failure recovery request related to coordinationnetwork equipment.

In this embodiment, transmitting the configuration information to theuser equipment may be performed when communications between the networkequipment and the user equipment begins, that is, the resource fortransmitting the beam failure recovery request is configured for theuser equipment at the beginning of the communications. In thisembodiment, for a certain piece of user equipment, step 201 may beexecuted by a coordination network equipment or by a serving networkequipment. Executing step 201 by the coordination network equipment andexecuting step 201 by the serving network equipment shall be describedbelow respectively.

First, the case where the coordination network equipment executes step201 shall be described.

In step 201, when the user equipment is used as the coordination networkequipment, the configuration information may be transmitted to the userequipment via a system information block (SIB) or remaining minimumsystem information (RMSI) of the coordination network equipment. Forexample, the configuration information may be transmitted via the SIB orRMSI of the coordination network equipment in which the beam failureoccurs, and the configuration information may be transmitted togetherwith configuration information on the transmission resource of the beamfailure recovery request of user equipment connected to the coordinationnetwork equipment and/or configuration information on a transmissionresource of a random access preamble.

In step 201, the coordination network equipment may transmit theconfiguration information via the system information block or theremaining minimum system information to the user equipment establishingcommunications with the coordination network equipment and not connectedto the coordination network equipment, or transmit the configurationinformation via the system information block or the remaining minimumsystem information of the coordination network equipment to userequipment establishing communications with the coordination networkequipment and not connected to the coordination network equipment anduser equipment connected to the coordination network equipment. That is,the configuration information may be used to configure a transmissionresource of a beam failure recovery request of user equipmentestablishing communications with the coordination network equipment andnot connected to the coordination network equipment, and may also beused to jointly configure a transmission resource of a beam failurerecovery request of user equipment connected to the coordination networkequipment. In this embodiment, before step 201, the serving networkequipment may transmit at least one of cell ID information of thecoordination network equipment, internal ID information of acoordination set of the coordination network equipment, global IDinformation of the coordination network equipment, beam pair link IDinformation of the coordination network equipment, and other related IDinformation of the coordination network equipment to the user equipment.

In this embodiment, the coordination network equipment refers tocoordination network equipment in which beam failure occurs, the cell IDinformation is, for example, a cell number of a cell where thecoordination network equipment is located, the global ID information ofthe coordination network equipment is, for example, a global number ofthe coordination network equipment, the internal ID information of acoordination set of the coordination network equipment is, for example,a network equipment number in a coordination network equipment set, andthe other ID information may be, for example, ID information implicitlyindicating the coordination network equipment, such as a time domaintransmission resource number to which the coordination network equipmentin transmission corresponds, or a frequency domain transmission resourcenumber, or the like.

In this embodiment, the serving network equipment transmits at least oneof the cell ID information of the coordination network equipment, theinternal ID information of a coordination set of the coordinationnetwork equipment, the global ID information of the coordination networkequipment, the beam pair link ID information of the coordination networkequipment, and the other related ID information of the coordinationnetwork equipment to the user equipment, so that the user equipment maydecode the SIB or the RMSI of the coordination network equipment. Forexample, the coordination network equipment transmits the ID informationto the user equipment via broadcast signaling (MIB or SIB) or RRCsignaling, and the user equipment may use the ID information to decode amaster information block (MIB) of a cell where the coordination networkequipment is located to obtain scheduling information on SIB/RMSI, anddecode NR-PDCCHs needed by the SIB/RMSI. For example, the user equipmentmay use the cell ID to scramble the NR-PDCCH and NR-PDSCH, and learnfrom the ID information of the coordination network equipment whichcoordination network equipment needs to be performed beam failurerecovery.

In this embodiment, after decoding the SIB or RMSI of the coordinationnetwork equipment, the user equipment may obtain the configurationinformation of the transmission resource used for configuring the beamfailure recovery request information in the SIB or the RMSI, and theuser equipment may use a random access preamble sequence and transmitthe beam failure recovery request information on a non-contentionchannel of a physical random access channel (PRACH).

Next, the case where the serving network equipment executes step 201shall be described.

In step 201, when the user equipment is used as the serving networkequipment, the configuration information may be transmitted to the userequipment via signaling of a radio resource control (RRC) layer of theserving network equipment.

In step 201, the configuration information may be transmitted tospecific user equipment. For example, the configuration information istransmitted to the user equipment connected to the serving networkequipment, such as transmitting the configuration information to userequipment connected to the serving network equipment and having anidentical set of coordination network equipment.

In this embodiment, the configuration information may includetransmission resource configuration of the transmission beam failurerecovery request information when beam failure occurs respectively inrelevant serving network equipment and coordination network equipment ofspecific user equipment, for example, the configuration informationincludes transmission resource configuration of the transmission beamfailure recovery request when beam failure occurs respectively in theserving network equipment and coordination network equipment of the userequipment connected to the serving network equipment. Transmissionschemes adopted by the pieces of user equipment may be different, suchas a service scheme of single network equipment, and a service scheme ofmultiple pieces of network equipment; and furthermore, the sets ofcoordination network equipment may possibly be different.

In this embodiment, the configuration information may include not onlythe configuration of the transmission resource corresponding to the beamrecovery request information of the coordination network equipment wherethe beam failure occurs, but also configuration of a transmissionresource of beam recovery request information when beam failure occursin the serving network equipment itself. That is, the configurationinformation may include configuration of transmission resourcescorresponding to beam recovery request information of all networkequipment in communications with the user equipment.

In this embodiment, there may exist multiple resources for transmittingthe beam recovery request in the configuration information, and afterreceiving the configuration information, the user equipment may randomlyselect one or more transmission resources from the configuredtransmission resources to transmit the beam recovery request informationwhen beam failure occurs.

In this embodiment, the serving network equipment may also perform someother configuration in configuring the resource for transmitting thebeam recovery request for the user equipment. For example,quasi-co-location hypothesis configuration information related to theNR-PDCCHs and/or physical resource configuration information of acontrol resource set (CORESET) of the NR-PDCCHs, etc., of the servingnetwork equipment and the coordination network equipment may also betransmitted. Such information may be used, for example, to detect eventsof beam failure. For example, in order to differentiate the NR-PDCCHconfiguration information of the serving network equipment and thecoordination network equipment, the quasi-co-location hypothesisconfiguration information and/or the physical resource configurationinformation of the control resource set of the NR-PDCCHs may beconfigured in a grouping form, with only a group number being known tothe user equipment; and the ID information of the serving networkequipment and the coordination network equipment may be added into theuser equipment to differentiate the configurations of the multipleNR-PDCCHs when the above information is configured.

It can be seen from the above embodiment that with the embodiment ofthis disclosure, a case where beam failure occurs in the coordinationnetwork equipment may be dealt with efficiently, and normalcommunications between the network equipment and the user equipment maybe ensured.

Embodiment 7

The embodiment of this disclosure provides a method for responding abeam failure recovery request, applicable to a network equipment side.FIG. 8 is a flowchart of the method for responding a beam failurerecovery request of Embodiment 7 of this disclosure. As shown in FIG. 8, the method includes:

Step 801: response information related to a beam failure recoveryrequest of coordination network equipment is transmitted to userequipment.

In this embodiment, for a certain pieces of user equipment, step 801 maybe executed by the coordination network equipment or by the servingnetwork equipment. Executing step 801 by the coordination networkequipment and executing step 801 by the serving network equipment shallbe described below respectively.

First, the case where the coordination network equipment executes step801 shall be described.

In this embodiment, for the coordination network equipment, before step801, the method may further include:

Step 802: a beam failure recovery request related to the coordinationnetwork equipment is received from the user equipment or serving networkequipment.

In this embodiment, the beam failure recovery request may be received bythe coordination network equipment, or may be forwarded by the servingnetwork equipment to the coordination network equipment after receivingthe beam failure recovery request, and a manner of receiving the beamfailure recovery request is not limited in this embodiment.

In step 801, a manner in which the coordination network equipmenttransmits the response information may be identical to or different froma manner in which the serving network equipment responds to the beamfailure request.

For example, access-related information, such as a random accessresponse or contention resolution of a contention-based random accessprocedure, may be included when the serving network equipment transmitsthe response information of the beam failure request. Hence, theresponse information in step 801 may include or may not include theaccess-related information.

In step 801, the coordination network equipment may transmit theresponse information by transmitting a data channel to the userequipment.

For example, the method may further include: transmitting a controlchannel used for scheduling the data channel to the user equipment.

For example, the coordination network equipment may transmit theresponse information by transmitting an NR-PDSCH to the user equipment,wherein the NR-PDSCH needs to be scheduled by transmitting an additionalNR-PDCCH by the coordination network equipment, and scramblinginformation of CRC of the NR-PDCCH is determined by the transmissionresource of the beam failure recovery request information selected bythe user equipment, for example, a calculation method thereof is similarto RA-RNTI calculation in an LTE system.

Next, the case where the serving network equipment executes step 801shall be described.

In this embodiment, for the serving network equipment, before step 801,the method may further include:

Step 803: a beam failure request related to the coordination networkequipment is received from the user equipment or the coordinationnetwork equipment.

In this embodiment, the beam failure recovery request may be forwardedby the coordination network equipment to the serving network equipmentafter receiving the beam failure recovery request, or may be directlyobtained from the user equipment, and a manner of receiving the beamfailure recovery request is not limited in this embodiment.

Before step 801, the method may further include:

Step 804: a part of or all information included in the responseinformation is received from the coordination network equipment.

For example, the response information may include at least one of cellID information of the coordination network equipment where a beamfailure event occurs, internal ID information of a coordination set ofthe coordination network equipment, global ID information of thecoordination network equipment, beam pair link ID information of thecoordination network equipment, and other related ID information of thecoordination network equipment.

For example, the response information may further include a userequipment identifier (UE ID) for transmitting the beam failure request,such as a UE number, and may further include new candidate beam relatedinformation, such as a quasi-co-location hypothesis, and a beam ortime-frequency resource number of a new candidate beam, etc.

In this embodiment, for example, the coordination network equipmenttransmits the part of or all the information included in the responseinformation to the serving network equipment via an Xn interface.

In step 802, the response information may be transmitted to the userequipment via a data channel of the serving network equipment.

For example, the serving network equipment may transmit the responseinformation of the beam failure request related to the coordinationnetwork equipment to the user equipment via the NR-PDSCHs. The CRCscrambling information of the NR-PDCCHs scheduling the NR-PDSCHs isdetermined by the transmission resource of the beam failure recoveryrequest information selected by the user equipment, for example, acalculation method is similar to RA-RNTI calculation in an LTE system.In this embodiment, the serving network equipment transmits the responseinformation of the beam failure request related the coordination networkequipment to the user equipment, and furthermore, when beam failureoccurs in the serving network equipment and the beam recovery request isreceived from the user equipment, the serving network equipment alsoneeds to transmit response information of a beam failure request relatedthe serving network equipment itself to the user equipment. In such acase, in order to differentiate above two pieces of responseinformation, the types of response information may be divided into twotypes. For example, type 1 denotes the response information of a beamfailure request related the serving network equipment itself, and type 2denotes the response information of the beam failure request related thecoordination network equipment.

In this embodiment, the response information of type 1 and type 2 may bedefined as having different formats, or may be defined as havingidentical formats. Furthermore, the response information of type 1 andtype 2 may be defined as having identical sizes for mutualcompatibility. It is also possible that types responses are notdifferentiated, but a related ID of the network equipment in which anevent of beam failure occurs is included in the response information,such as transmitting at least one of cell ID information of the servingnetwork equipment or the coordination network equipment where a beamfailure event occurs, the internal ID information of a coordination setof the coordination network equipment, the global ID information of thecoordination network equipment, the beam pair link ID information of thecoordination network equipment, and other related ID information of thecoordination network equipment to the user equipment. For example, thecoordination network equipment refers to coordination network equipmentin which beam failure occurs, the cell ID information is, for example, acell number of a cell where the coordination network equipment islocated, the global ID information of the coordination network equipmentis, for example, a global number of the coordination network equipment,the internal ID information of a coordination set of the coordinationnetwork equipment is, for example, a network equipment number in acoordination network equipment set, and the other ID information may be,for example, ID information implicitly indicating the coordinationnetwork equipment, such as a time domain transmission resource number towhich the coordination network equipment in transmission corresponds, ora frequency domain transmission resource number, or the like.

In the present embodiment, the method may correspond to the processingof Embodiment 1, or may not correspond to Embodiment 1. And whetherthere exists a correspondence therebetween is not limited in thisembodiment.

It can be seen from the above embodiment that with the embodiment ofthis disclosure, a case where beam failure occurs in the coordinationnetwork equipment may be dealt with efficiently, and normalcommunications between the network equipment and the user equipment maybe ensured.
